Fundamentals of analog filter design and linear circuits are covered in a book and kit of parts that are available on ...

Investigating potential power current sources capable of handling both AC and DC currents using the LM317 current source.

For that matter, what's an ohm? While impedance technically does matter, it's not quite as cut and dry as saying "speakers with X impedance should only be connected to receivers with Y impedance." ...

The "Low equivalent series resistance," or "low impedance" aluminum capacitors at issue, contained an electrolyte solution that, when doing its job, served as a cathode and kept the paper ...
